The 13-year-old freestyle skier, from Dronfield Woodhouse and a student at Dronfield Henry Fanshawe School, is a member of the England Park and Pipe team having won the British Under-16s Championship for Rails, finished second in half pipe and third in slopestyle.
Millie says: "My current weekly training regime starts on Monday evening when I have trampoline training for an hour at Ponds Forge, Sheffield.
"Tuesday sees me travelling to Tamworth in Staffordshire for freestyle ski training. Wednesday is a free night, I use this free time to visit my local gym and catch up on any outstanding homework/school work.
"Thursday and Friday see me travelling to Xscape at Castleford for more freestyle training. Every alternate Saturday sees me journey to Halifax for yet more freestyle training.
"My season's goals are to enter as many competitions as I can and hopefully go to as much training abroad as I can. So far this season I have entered The British Championships, where I took first Overall Female, making me the British 2015 Champion.
"My sporting ambitions are to carry on with my training to be the best I can. I am working on being selected to train with the GB Team, which will hopefully lead onto me being selected to represent my country in the 2022 Olympics."
